This interactive map shows an estimate of the last known possible positions of MH 370 (somewhere inside the blue annulus) and the estimated distance it could travel based on average speed (the green annulus). In a scenario where MH 370 has not stopped to refuel, its last known position would likely be somewhere inside the intersection of the green and blue annuli. Information is based on the final confirmed position of MH 370 above the island of Pulau Perak at 2:14 am (source) and a flight time of 6 hours thereafter at a speed of between 70% and 100% of a 777's cruise speed of Mach 0.84 (source). The location of the blue annulus is based on the likelihood that the satellite used to calculate the position ring was Inmarsat-3 F1 (source).
Thanks to Nrg800 of the Flyertalk MH 370 thread for the inspiration.
